Tunnel Greenhouses - Buy direct from NZ manufacturer

Our most popular home garden tunnelhouses use sturdy 32mm square aluminium for the frame hoops. They are 2.36 metres wide and come in eight different lengths.
Super long-life Duratough 210 micron thickness clear greenhouse film is used for the covering which has a 10 year + service life. Duratough film is also used on Redpaths commercial greenhouse designs - it locks in night-time temperatures whilst transmiting superior light levels to your crop for quality plants during the day.

All of the main framework is durable aluminium and we include a 60mm x 30mm aluminium base rail so that there is no timber to rot or steel to rust at the ground contact points. A smooth sliding aluminium door and 3 blade glass louvre rear window is also included on all models. Selected longer models have a large 1.6m length roof vent and this may be fitted with a thermic ram option to open and close it automatically (no power required). To save you assembly time we deliver the greenhouses 50% assembled with the end walls, louvre window mechanism and door frame made up.
Redpath is New Zealands longest and largest established commercial and domestic greenhouse manufacturer and a trusted brand. We proudly manufacture these tunnel houses to meet New Zealand gardeners needs.
